Discuz7.2 IE9兼容性写法 杜工完全修补方案

前端技术 2023/09/09 CSS
现象:
1. IE9快速发帖不跳转
2. IE9管理员处理帖子失败
3. IE9登录不跳转,需要手动刷新

原因:

1. AJAXPOST函数判断out了
2. 动态创建iframe时各浏览器处理方式不同

解决方法:

1. 修改templates/header.htm

<meta http-equiv=”x-ua-compatible” content=”ie=7″ />
替换为

复制代码
代码如下:

<!–[if lte IE 8]>
<meta http-equiv=”x-ua-compatible” content=”ie=7″ />
<![endif]–>
<!–[if IE 9]>
<meta http-equiv=”x-ua-compatible” content=”ie=9″ />
<![endif]–>



2.修改include/js/common.js

把ajaxpost函数替换为:


复制代码
代码如下:

function ajaxpost(formid, showid, waitid, showidclass, submitbtn, recall) {
var waitid = typeof waitid == \'undefined\' || waitid === null ? showid : (waitid !== \'\' ? waitid : \'\');
var showidclass = !showidclass ? \'\' : showidclass;
var ajaxframeid = \'ajaxframe\';
var ajaxframe = $(ajaxframeid);
var formtarget = $(formid).target;
var handleResult = function() {
var s = \'\';
var evaled = false;
showloading(\'none\');
try {
s = $(ajaxframeid).contentWindow.document.XMLDocument.text;
} catch(e) {
try {
s = $(ajaxframeid).contentWindow.document.documentElement.firstChild.wholeText;
} catch(e) {
try {
s = $(ajaxframeid).contentWindow.document.documentElement.firstChild.nodeValue;
} catch(e) {
s = \'内部错误,无法显示此内容\';
}
}
}
if(s != \'\' && s.indexOf(\'ajaxerror\') != -1) {
evalscript(s);
evaled = true;
}
if(showidclass) {
$(showid).className = showidclass;
if(submitbtn) {
submitbtn.disabled = false;
}
}
if(!evaled && (typeof ajaxerror == \'undefined\' || !ajaxerror)) {
ajaxinnerhtml($(showid), s);
}
ajaxerror = null;
if($(formid)) $(formid).target = formtarget;
if(typeof recall == \'function\') {
recall();
} else {
eval(recall);
}
if(!evaled) evalscript(s);
ajaxframe.loading = 0;
$(\'append_parent\').removeChild(ajaxframe);
};
if(!ajaxframe) {
try{
ajaxframe = document.createElement(\'<iframe name=\"\' + ajaxframeid + \'\" id=\"\' + ajaxframeid + \'\"></iframe>\');
}catch(e){
ajaxframe = document.createElement(\'iframe\');
ajaxframe.name = ajaxframeid;
ajaxframe.id = ajaxframeid;
}
ajaxframe.style.display = \'none\';
ajaxframe.loading = 1;
$(\'append_parent\').appendChild(ajaxframe);
} else if(ajaxframe.loading) {
return false;
}
_attachEvent(ajaxframe, \'load\', handleResult);
showloading();
$(formid).target = ajaxframeid;
$(formid).action += \'&inajax=1\';
$(formid).submit();
return false;
}



后台刷新缓存,搞定。
